FLORY W. LEMAY, OF LAVJRENCIE, MASSACHUSETTS, ASSIGNOR OF ONE-HALF TO CLEMENT PERONT, 0F LAWRENCE, MASSACHUSETTS.

DISPLAY-RACK.

To all whom it may concern:

Be it known that I, FLoRY 7. LEMAY, a citizen of Canada, residing at Lawrence, in the county of Essex and State of Massachusetts, have invented certain new and useful Improvements in Display-Racks, of which the following is a specification.

This invention relates especially to racks for displaying such heavy sheet material as linoleum or oil cloth, but it may be used for displaying carpets or other similar material.

In handling linoleum which is usually put up in rolls six feet or more in width, on account of the great weight, the clumsiness of the rolls and of the material, a satisfactory display rack is difficult to obtain. It is especially desirable with such heavy material that any great amount of lifting should be avoided and that as many rolls as possible should be crowded into a small space to save floor space.

In the drawings, Figure 1 is a top view of a rack of my construction. Fig. 2 is a side view. Fig. 3 is a detail of one roll and its bearings. Fig. 4 is a section of a modification of the upper bearing holders. Fig. 5 is a section on line K Y of Fig. 3. Fig. 6 is a detail of the free revoluble base or turntable. Fig. 7 is a detail of one of the pivoted revoluble bases or turn-tables.

The back bone of my rack comprises two uprights 10 and 1l connected by a strong beam 12. Both uprights are rmly attached to the floor B and one of the uprights 10 may be firmly attached to the wall A.

Arranged in a staggered manner are the revoluble pivoted bases or turn-tables 20, 21, 22 and 23. These are arranged on the floor in pairs 21, 23 below and on each side of beam l2 near each other, then a pair 20, 22 a sufficient distance to clear the first two, then a pair near each other, then a pair away from each other in the manner shown. Each base comprises a disk 30, see Fig. 7 which is preferably of metal but may be of wood. In the center of disk 30 is a stud 31 whose outward curvature is inside of a curve struck from near the outer edge of the disk as shown in Fig. 7. This revoluble base stud is preferably set into the disk, and through it is passed the headed bolt 32. This bolt 32 also passes into and through a metallic bearing plate which rests upon and is attached to a board or false floor 41 in which is a recess 42 to receive the end of the bolt Specification of Letters Patent.

32 and the lower nut 43 thereon. Nut 43 and a nut 44 above the metal plate 40 hold the revoluble base bolt 32 firmly in place. If the disk 30 is of metal, I prefer to turn down the rim at 33 as shown, and in any case the disk is supported by casters 34 which help to carry the weightl of the rolls of material D placed thereon. Each of these pivoted revoluble bases 20, 21, 22, 23 rotates with very little friction upon its caster as they rest on metal bearing plate 40 and around the revoluble base bolt 32 as a pivot.

Arranged directly above the rotary bases are long bearing holders E and short bear ing holders F at the end of which are upper bearings which are directly over the revoluble base studs. These upper bearing holders preferably are made in two parts one of which 71 is a bracket and is fixed to the beam 12. This terminates in a slotted end 57 which receives the flanged end 58 of an arm 52. End 58 slides into slotted end 57 and arm 52 supports the upper bearing stud as shown. A pin 53 holds the bracket 71 and arm 52 together. The upper bearingr comprises a pin 54 which passes downward freely through a hole in arm 52 and carries wooden bearing stud 50 which is attached thereto by means of a screw 5G.

In operation, when a new roll is to be placed in position, the upper arm 52 with upper bearing stud 50 is removed and the upper bearing stud 50 is placed in the hollow center customary in such rolls. The roll is lifted onto a revoluble base and tilted as shown by the dotted lines in F ig. 3 and the flanged end 58 of arm 52 is inserted in the groove of the bracket member 71. It will be observed that as the roll of material D is being moved from the diagonal position to the vertical position, the revoluble base stud 31 enters the hole in its bottom and as the'roll continues toward the vertical position, the end 58 of arm 52 enters the groove in bracket end 57. The arm and bracket are now pinned together by pin 53 and the roll is permanently fastened in position. The upper bearing stud 50 and the revoluble base stud 31 hold the roll of material D firmly in place and prevent the roll from being displaced as it is unwound or wound up.

. It is evident that, as shown in Fig. 1, the

material D may be unwound in a vertical position and reivound with very little trouble. I prefer however, to use a free revo-luble base II which comprises a disk G0 and casters 6l together With a central stud G2. As shown in Fig. l, the end of the material D can be rested upon this free revoluble base II and Wound up after being measured.

The upper bearing holders may be modi.- iied as shown in Fig. 4A. In this case the slot in bracket 5l is open at the bottom so that the flanged end TS of the upper bearing holder instead of sliding into it horizontally, can be pushed up from below as the roll is being put| into place. In such case, I prefer to use a knurled thumb nut 'T3 which enters suitable threads in tlanged end TS whereby the parts are held iirmly in place.

Other modilications of my device will occur to others but my principal idea is the turn-tables or revoluhle bases each with a central stud and the detachable arms carrying thel upper bearings directly over the centers of the studs in the revoluble bases. I prefer to use the uprights with connecting beams and the bases and long and short bearing holders arranged in pairs and staggered as shown.

That I claim as my invention and desire to cover by Letters Patent, is:

l. In a rack for heavy sheet material, the combination with a. tioor ot' uprights, a beam which connects said uprights, and revoluble bases arranged in pairs on each side of said beam the members oft' each adjoining pair being at diilerent distances 'from each other and each revoluble base being pivotally attached to the tloor and having central studs and casters which rest on the tloor, with upper bearing holders so attached to the beam as to extend over said revoluble bases each arm having a depending bearing stud directly over a stud in a revoluble base as described.

2. In a rack for heavy sheet material, the combination with a floor, of ay revoluble base having a cent 1al stud and pivoted to said floor, a support, an upper bearing holder attached to said support and having a. detachable arm, and a bearing stud carried thereby as described,

3. In a rack for heavy sheet material, the combination with a floor of uprights, a beam which connects said uprights, and revoluble bases pivoted to the floor and arranged in pairs on each side of said beam, the members of each adjoining pair being at dilterent distances from each other and each revoluble base having a central stud, with upper bearing holders so attached to the beam as to extend over the revoluble bases each having a detachable arm which carries a depending bearing stud directly over a stud in a revoluble base, and a free revoluble base in operative relation with said rack, as described.

In testimony whereof I hereto aiiix my signature in presence of two witnesses.
